and more particularly to'a double'tubular or V- section stud, formed ofstrip or sheet metal of suitable cross sectional dimensions to be usedas studs in a partition, or other wall, and providing nailing grooves onopposite sides of the stud to which metal lath, plaster board or otheraccessory material for forming walls may be quickly" and easily appliedas by nails, screws or similar fastening means. y

In my prior application, Serial No. 640,820, for V-Section StructuralMembers, filed January 12, 1946, and now abandoned, I disclosed a metalstud formed of two similar structural members of V-section connectedtogether so as to provide nailing grooves on opposite sides of the stud,and the present invention is an improvement upon such studs, as itprovides an integral, structural member of sufficient cross sectionalwidth to form a stud of conventional size, having a nailing groove ineach side. g

It is therefore an object of the present invention to provide a doubletubular or V-section structural stud of simple and'inexpensiveconstruction which may be rolled or otherwise formed to any sizerequirements.

Another object is to provide such a stud which may be economicallyproduced from one of the most inexpensive forms of raw steel strips.

A further object is to provide a double V-sec tion structural stud inwhich the metal is placed where the requirement is the greatest.

A still further object is to provide a structural stud having maximumefiiciency with a minimum amount of metal. Another important object isto provide a structural stud so constructed'that it provides nailinggrooves on opposite sides of the stud, to which accessory buildinmaterial, such as metal lath, plaster board and the like, may be easilyattached as by nails, screws or other fastoning devices.

It is also an object of the invention to provide a double tubular orV-section structural stud having nailing slots or grooves the Walls ofwhich are rigid and held to a definite spacing regardless of thediameter of the nails or other fastening devices to be driven therein.

A further object is to provide a doubletubular or V-section structuralstud in which the walls of the nailing grooves present substantialsurfaces to grip and retain the nails or other fastening devices driveninto the grooves.

A still further object of the inventionis the provision of a doubletubular or V-section stud of the character referred to in which thewalls of 4 Claims. (Cl. 189-34),

the nailing grooves are each formed upon a substantial radius so as todirect'the nails, or other fastening devices, into the grooves. I

Another object is to provide such a stud in which the walls ofthegrooves are so shaped as to bend the nails, or other fasteningdevices, driven into the grooves so as to provide an additional hold onthe fastening devices.

The above and other objects apparent from the drawings and followingdescription, may be attained, the above described difficulties overcomeand the advantages and results obtained, by the apparatus, construction,arrangement and combinations, subcombinations and parts which comprisethe present invention, preferred embodiments of which, illustrative ofthe best mode in which applicant has-contemplated applying theprinciple, being set forth in detail in the following description andillustrated in the accompanying drawings, in which:

Fig. 10 a'similar view of the type of stud illustrated in Fig. 5. v

Referring now more particularly to the embodiments of the inventionillustrated in the drawings, in which similar numerals refer to similarparts throughout, as shown in Figs. 1 and 6 the double V-sectionstructural stud may be rolled or otherwise formed from a strip or sheetof steel; or other suitable metal of necessary or desired Fig. 6,showing the form gauge and of uniform width sufficient to produce thedesired cross section.

The central portion of the strip forms the center or inner wall I5,extending transversely through the strip at right angles to the oppositefaces of the stud. At the edges of this central wall the strip isoppositely bent arcuately as indicated at [6, upon a considerableradius, which as shown is more than twice the thickness of the metal,and then extended in opposite directions, at right angles to the centralwall l5, forming the flat outer walls H, the strip being again bent upona considerable radius, as indicated at l8 and merging into the angularouter walls l9, forming the two similar, oppositely disposed V-sections,as indicated at 20.

At the apices of the V-sections the strip is again bent arcuately inopposite directions, upon the same radius as the bends l6, as indicatedat 2|, and terminates in the oppositely disposed, fiat flanges 22,located in the plane of the fiat end walls I! of the V-sections.

A longitudinal groove or slot 23 is thus formed in the apex of eachV-section, through which nails, screws or other fastening devices may bedriven to secure metal lath, wall board or other accessory buildingmaterial to opposite faces of the stud, in order to form a partition orother wall.

If desired, in order to hold the width of the grooves, or slots, 23 to adefinite spacing, preferably less than the diameter of the nails orother fastening devices to be driven therein. as well as to stiffen andreinforce the structural stud and hold it rigidly in the formedposition, each groove or slot 23 may be welded, riveted or otherwiseconnected at spaced intervals, as indicated at 24.

As shown in Fig. 6 metal lath, plaster board, wall board or otherbuilding accessory for forming an inside finish for a wall or partition,may be quickly and easily attached to Opposite faces of the stud bynails or the like driven into the nailing grooves or slots 23.

For the purpose of illustration metal lath, as

on the other side of the stud a sheet of plaster board, wall board,plywood, insulation board, or the like as indicated at 21 may beattached to the adjacent face of the stud by nails 28 driven into thenailing groove 23 onthat side of the stud.

The nails, screws or other fastening devices being preferably of largerdiameter than the width of the nailing grooves 23 will cause the same tobe tightly wedged into the grooves 23 when they are driven therein, soas to securely hold the accessory building material upon opposite sidesof the stud.

In the modification shown in Figs. 2 and '7, the central wall la-islocated at a considerable angle, whereby the two V-sections aresymmetrical and the nailing grooves 23a at the apices thereof are spacedfurther from the transverse center line of the stud.

For this purpose the outer walls I So. of the V-sections are located ata lesser angle than the walls IS in Figs. 1 and 6. Otherwise the studshown in Figs. 2 and 7 may be the same as above described and accessorybuilding material may be attached thereto by nails or the like driveninto the nailing grooves 23a.

The modification shown in Figs. 3 and 8 has certain advantages notattained in the forms of stud above described. First, the nailinggrooves 23b, on opposite sides of the stud, are located in thetransverse center line of the stud, directly opposite to each other.

Furthermore, because of the angular location of the center wall l5b, thenails, or other fastening devices, used to attach accessory buildingmaterial to the stud are caused to bend to one side as they are driveninto the grooves 23b as indicated at 261), thus giving an additionalhold on the nails.

In the double tubular type of stud shown in Figs. 4 and 9 the structureis quite similar to that shown in Figs. 1 and 6, the central wall l5cbeing at right angles to the opposite faces of the stud. The tubularsections 200, formed on each side of this central wall, are of lesswidth than in theforms of the invention above described, the closed endsthereof being of semi-cylindrical shape as indicated at I10. Otherwisethis section may be as above described and accessory build.- ingmaterial may be attached thereto by driving nails 26c into the nailinggrooves 230 on opposite sides of thestud.

The form of stud shown in Figs, 5 and 10 is substantially the same asthat shown in Figs. 4 and 9. excepting that the entire stud is distortedangularly, the central wall I5d being on a considerable angle and thetwo tubular or V-sections 20d, formed on each side thereof, beingcorrespondingly located at a considerable angle. The nailing grooves2311 are necessarily located much further from the transverse center ofthe stud than in the other forms of the invention above described.

This form of stud has the advantage of considerably bending the nailsused for attaching accessory building material to each side of the stud,as indicated at 26d, making an additional hold on the nails or otherfastening devices.

Another advantage of a stud made in the manner described and illustratedherein is that owing to its structural shape it may be formed of verylight gauge sheets or strips, whereby such studs may be economicallyproduced.

According to the provisions of the patent statutes I have explained theprinciple of my invention and described several preferred embodimentsthereof, but ,I desire to have it understood that within the scope ofthe appended claims, the invention may be practiced otherwise than asspecifically illustrated and described, the invention residing in theformation of a stud from a single piece of sheet metal so formed as toproduce two oppositely disposed tubular or V-.-sections forming nailinggrooves at opposite sides of the stud.
